TSOP IR Receiver interface with arduino
TSOP IR Receiver Tsop is an IR receiver which will help you to interface your TV remote with arduino. The TSOP outputs a constant HIGH signal when idle and as it receives data, it tends to invert the data. i.e when an IR LED is transmitting data onto the TSOP, every time the IR led goes high, the TSOP will go LOW and vice versa. Remote control signals are often bytes of data that is encoded and transmitted by pulsing(switching ON & OFF the IR LED at a specific frequency) Most TV remote controls work at 32-40 Khz frequency and most receivers can receive this range. The SIRC protocol uses a pulse width encoding of the bits. The pulse representing a logical "1" is a 1.2ms long burst of the 40kHz carrier, while the burst width for a logical "0" is 0.6ms long. All bursts are separated by a 0.6ms long space interval. Modulation If you look at the image, you can see the the 1.2ms high of the Logical '1' has further black lines with spaces in ...
